attenuator
Definitions
A device that reduces the amplitude or power of a signal without appreciably distorting its waveform.
A substance or agent that reduces the virulence of a pathogenic microorganism or the intensity of a stimulus.
Examples
The engineer installed an attenuator in the circuit to reduce the signal strength and prevent distortion.
A variable attenuator was used during the testing phase to precisely control the intensity of the laser beam.
